Document Summary
The water cycle and rivers: surface processes, driven by: Solar energy: drives weather, climate, and water cycle. Gravity: drives landslides, direction of water flow, water plays a critical role, water, exists in three states on earth. Solid, liquid and gas: universal solvent. More compounds dissolve in water than any other substance: has a high heat capacity, solid is less dense than liquid. No scientific definition of a river, everything is called a stream. Stream principles are the same regardless of size: streams flow downslope to their base level . The faster a stream flows, more and heavier material can be carried. Slow streams can carry only the finest material: types of streams. Where runoff and groundwater flow to a single stream: watershed. Surface area of a drainage basin: tributaries and stream order. Width (w: width x depth = cross sectional area, a. Velocity (v) thru a cross section, a: q = w d v = av.
